ZhongMingTech/Ming1.0-Base

Introduction

The Ming large language model (Ming‑LLM) is a domain‑specialized LLM for the energy sector.

• We release both the base model and the supervised fine‑tuned (SFT) variant.
• The Ming base model is initialized from the Qwen2.5‑72B base model and is subsequently adapted via continued pretraining on a high‑quality energy‑domain corpus.
• The SFT variant is initialized from the Ming base model and is trained on instruction‑tuning datasets, including conversational QA, sentiment analysis, and information extraction, among others.
• Both models demonstrate improved performance across the C‑Eval, CMMLU, MMLU, GSM8K, and IFEval benchmarks.

Inference

You can use Ming model with the standard HuggingFace transformers library:

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, TextStreamer

dtype = torch.bfloat16
device_map = "auto"

model_path = /model/path
tokenizer = AutoTokenizer.from_pretrained(
    model_path, use_fast=True, trust_remote_code=True
)
model = AutoModelForCausalLM.from_pretrained(
    model_path, torch_dtype=dtype, device_map=device_map, trust_remote_code=True
)

messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user",   "content": "who are you?"} 
]

prompt = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

with torch.no_grad():
    output_ids = model.generate(
        **inputs,
        max_new_tokens=256,
        do_sample=True,
        temperature=0.3,
        top_p=0.9,
        repetition_penalty=1.1,
        eos_token_id=eos_token_id,  
        pad_token_id=(tokenizer.pad_token_id or tokenizer.eos_token_id),
        streamer=None 
    )
gen_ids = output_ids[0, inputs["input_ids"].shape[1]:]
text = tokenizer.decode(gen_ids, skip_special_tokens=False)

Bias, Risks, and Limitations

• Like any base language model or fine-tuned model without safety filtering, these models can easily be prompted by users to generate harmful and sensitive content.
• Such content may also be produced unintentionally, especially in cases involving bias, so we recommend that users consider the risks when applying this technology.
• Additionally, many statements from Ming Model or any LLM are often inaccurate, so facts should be verified.
